In Pixar's Cars 2, what is the name of the international racing event?

The international racing event in Pixar's Cars 2 is the World Grand Prix.

The World Grand Prix is organized by former racer Miles Axlerod to promote Allinol, a new alternative fuel. Lightning McQueen enters the competition and races in three countries, while Mater's mistaken identity draws him into the film's espionage storyline. The event supplies the movie with its international locations and its central sporting stakes.

The races take place in Tokyo, Porto Corsa, and London. Each course has a different visual identity, from Tokyo's illuminated streets to Porto Corsa's coastal setting and London's landmarks. The competition also introduces several international racers, including Francesco Bernoulli of Italy.

The World Grand Prix is fictional and should not be confused with the Piston Cup, the domestic racing championship associated with the first Cars film and with McQueen's career. Cars 2 uses both competitions, but they serve different roles in the story.
